2016 Subaru Impreza Wheel Hubs — Purpose, Care and When to Replace

Technical sources including the Subaru Factory Service Manual for the 2016 Impreza (GJ/GP), Subaru Genuine Parts catalogues, and major bearing manufacturers’ application guides confirm that this model uses bolt-in wheel hub assemblies (hub unit bearings) front and rear. So yes, wheel hubs are fitted and very relevant to the 2016 Subaru Impreza.

On a 2016 Impreza, the wheel hub assembly is the bit that the wheel and brake rotor bolt to, with a sealed bearing inside that lets the wheel spin smoothly around the knuckle. On AWD models, the driveshaft splines through the hub, so it’s doing double duty—supporting the wheel and transferring torque. The hub also carries the ABS encoder/tone ring, so it’s central to stability control and traction systems behaving properly.

They’re sealed-for-life units, which means no greasing or adjustment—too easy. That said, they do live a hard life. Aussie and Kiwi roads, coastal air, and the odd gravel detour can all add up. As part of regular servicing, it’s smart to:

• Listen for a humming or growling that changes with speed or while cornering.
• Check for play: gently rock the tyre at 12 and 6 o’clock once the car is safely lifted.
• Watch for ABS lights, uneven tyre wear, or a rotor running hot after a drive.
• Inspect for corrosion on mounting faces and studs.

If a hub’s noisy or loose, replacement is the fix. Best practice is to replace the complete hub assembly on the affected corner. Use quality parts matched to the VIN so the ABS encoder style is correct. During the job, clean the mating surfaces, fit new hardware where specified (especially axle nuts on drive wheels), and torque everything to Subaru specs—over- or under-tightening can kill a new bearing quickly. Avoid hammering on the hub
